      1. Will correct context to be Questionnaire.derivation
      2. Will change data type to be Coding
      3. Will revise the definition of 'extends' from:
        "Indicates this Questionnaire includes all of the items and permitted answers present in the target Questionnaire, however it also adds additional items and/or answers, such that a QuestionnaireResponse against the referencing Questionnaire may no longer be valid against the referenced Questionnaire."
        to
        "Indicates this Questionnaire includes all of the items and permitted answers present in the target Questionnaire, however it also adds additional items and/or answers.  A QuestionnaireResponse against the referenced Questionnaire should be valid against the referencing Questionnaire.  However, a QuestionnaireResponse against the referencing Questionnaire might not be valid against the referenced Questionnaire."

    Description

      Grahame Grieve: I have several issues with that extension

      • the context is wrong - it should be Questionnaire.derivedFrom, not Questionnaire.item
      • it should be Coding not CodeableConcept
      • The definition of 'extends' is unclear as to whether it is 'compliesWith+extends' or 'extends and breaks' - I interpreted it as the first in the validator
